A number of measurement points exist at different voltage levels on the network utilising a range of different measuring transducers in a variety of configurations. This proposal is aimed at developing a better understanding of the inherent accuracy of measurement transducers and to explore the options for either retrofitting new devices or calibrating the accuracy of existing devices.
Various issues will be investigated including:

  • Accuracy at minimum load

  • Accuracy at maximum load

  • Immunity against external disturbances (both AC and DC)

  • Cost

  • Ease of installation

  • Potential for tamper-proofing

The aim of the project is to be able to identify and assess the types (accuracy class, manufacturer, accuracy) of measurement transducers installed in identified locations and to provide a series of options to increase accuracy.
